CHAPTER REPORTS 

The Cornell Chapter 

During the academic year 191 5-16, ten meetings were held, at 
nine of which a scientific program was presented. Two meetings 
of especial interest were devoted to departmental demonstrations 
of research work under investigation by members in the depart- 
ment. The general policy of the chapter has been to invite the 
public to the lectures and demonstrations, and the large attendance 
in most cases has been good evidence of the interest shown in the 
work of the Society. The usual social hour for members and their 
wives was held immediately following many of the lectures. 

The list of meetings with speakers and dates is as follows :

Evolution, by Dr. T. H. Morgan of Columbia University,

gand, November 23.

nology laboratories, January 13.

of the Research Department of the Detroit Edison Co., 
February 17.

bers of the Department of Psychology, and inspection of 
the psychological laboratories, March 23.

Harper of the N. Y. State Conservation Commission; fol- 
lowed by business meeting and election of new members,

NOTES 



The Indiana Chapter has published a yearbook for 1916 which 
lists officers and members of the Chapter and the full program for 
the calendar year. One meeting is held in each month during the 
academic year and usually at each meeting two papers are read by 
resident members. The January meeting, however, is devoted to 
Convocation Week Reports by fifteen members and there are two 
meetings at which visiting scientists have delivered addresses. One 
unusual feature of the pamphlet is a full list of non-resident and 
former members of the Chapter. 

District of Columbia Chapter. — In the list of the Charter Mem- 
bers published in the Sigma Xi Quarterly, Volume 3, No. 2, 
June, 191 5, the name of Alden Archibald Potter, A.B. Minnesota, 
1909, Assistant Pathologist, Bureau of Plant Industry, U. S. De- 
partment of Agriculture, was omitted by a clerical error. 

M. W. Lyon, Jr., Secretary.
